An elastomeric mounting comprises an annular elastomeric diaphragm shaped to deform by both bending and shear over a normal working range to accommodate relative longitudinal movement between two members between which the diaphragm is located. The diaphragm is provided in combination with elastomeric axial buffer operable to restrain relative movement of the interconnected members outside the normal working range and elastomeric transverse load bearing to restrain relative transverse movements.

Elastomeric mounting

An elastomeric mounting suitable for providing a low frequency suspension for a road vehicle cab comprises an annular elastomeric diaphragm shaped to deform by both bending and shear over a normal working range to accommodate relative longitudinal movement between two members between which the diaphragm is located. A fluid chamber is defined by an annular space between two tubular rigid members and bonded axially by the elastomeric diaphragm and an annular seal. Fluid damping is provided in the fluid chamber, preferably by orifices contained within a buffer which restrains relative radial movement of the rigid members.

An elastomeric mounting comprises a plurality of elastomeric layers having a plurality of reinforcement layers interleaved between and bonded to the elastomeric layers wherein confronting surfaces of the reinforcement layers are of corrugated profile having a plurality of peaks and valleys and are arranged so that the peaks of one surface are aligned with the valleys of the other surface. The reinforcement layers may all be the same size and shape and maybe disposed either vertically above one another or in echelon.

Elastomeric mountings

A flexible coupling for transmitting torque between two relatively rotatable components comprises a plurality of connector members and resilient elements arranged alternately to form a ring in which alternate connector members are adapted for connection to a respective one of the components and each resilient element is disposed between confronting load transmitting surfaces which are inclined relative to the rotational axis of the coupling whereby axial loads are accommodated by the elements in compression and shear. An even number of members is provided for connection to each component and successive members which in use are connected to the same component are reversed so that under torque loads there is no net axial component of force acting on the members associated with a component.
